lBe it known that I, RICHARD C. MASON, a citizen of the United States, and a resident of'Tulsa, in the county of Tulsa and State of Oklahoma, have made certain new and useful Improvements in vVVelLMeasuring' Apparatus, of which the following is a speciiication. *Y i f This invention relates to animprovement inl well measuring apparatus of the type embodying driving wheels coacting with the cable, or sand line, to accurately measure the depth of a well., Y

The object of the invention is to provide an apparatus or" this character whereinjthe driving Wheels are positively constrained to partake ofga motion. corresponding vto the motion of the cable, the cable being rheld in driving engagement with the driving wheels `at all* times inl order to eect this operation. Y

A further object is ,to provide an apparatus of this character with extremely sim plerand yeteiiicient yand positively acting means for constraining the driving wheels to partake of motion in the same degree and in the samedirection. Y v Another object isjto provide a' deviceof this character which is of a simple-and durable construction, reliable .in operation and easy and inexpensive to manufacture. Other objects and advantages reside in certain novel features of construction, combination and arrangement of parts, which willbe hereinafter more fully described, and particularly pointed out inthe appended claims, reference being had to the accompanying drawing forming part of this specilication, and in which: l 4, Figure 1 is a view in Side elevation'illustrating` thej preferred embodiment ofthe invention, parts being broken away and parts being shown in section for the sake of illustration, and, A 4 i :Figure 2 is a view in transverse horizontal sectionon line 2-'2 of Fig. 1, parte being shown in elevation 'for thesake of yillustration. Y i

Referring to the drawings, wherein, for the-,sake of illustration isrshowngthe preferred embodiment of the invention', the sand line or cable which is adapted to extend down into the well is designated at C, and the apparatus which measures this sand line or cable and which consequently measures the depth of the well is indicated 'genorally at M 'and is adapted to be mounted upon" the upper lendl of the well casing ori the like.

.Y Thiswellmeasuring apparatus comprises a main frame designatedgenerally at 10 andl preferably constructed ofivmet'al, the .main

frameV includingsides" 11 and 12 having reinforcing ribs 13and 14, respectively, abot-v tom 1,5 and a top 16, ,the bottom and thetop beingl ofl relatively heavy construction, as

clearly shown inthe drawings. f 4'lhe'sidefll consists of a straight bar of metal curved at its ends into the top and bottoml and the yside 12vconsists of twosections f1.2/a and V12" angularly arranged with respecty to each other. The bottom 15 and'` top .16 `are providedv with U-shaped openings IZand 18 respectively, through` which the sand line vor cable() extendsgwhenthe device is lin use. i

Thel bottom' 15v and the to-p 1,6 vof the frame are pro-vided' with seats Yor notches indicated at 19 in which longitudinal bars 21 are seated, the 4bars being secured to the frame by boltsand nuts23.1 y v l `Driving Wheels25, 26 and 27 are arranged between a pair of thebars 21Aand-are mountyed Vupon axles 28, 29y and'BO -res] oectively,the driving wheels 25-,1and127 kbeing loosely mounted `on thelaxles 28 and 30 and the driving wheelv26A being fixed' to the'axle y29. VThe driving wheels vdirectly engage the sand 'line or cablefand receive' the mot-ion thereof.

Y Means is provided-fori.constraining the driving wheels tolvcorresponding motion and this means preferably comprises disks 31, 32,

and 33 secured to the driving wheels 25,

Ball hearings 0r aberv antfrfvtion means Such -astdesgneted et 37 er@ interposed, V10min/@er1 the periphery of the eccentric disks and the inner periphery of the annular portionsl or rings. i portions may embody a removable retaining ring having threaded connection therewith so as to'l facilitate the. assembly of the balls in the races Vprovided` therefor' inthe pek If desired, the disks or the annular Y bearing 42.provided therefor in the side 12 riphery of the eccentric disks and of the annular' ring portion.

Y The axle 29 extends for a substantial distance beyond the bar 21 in which it is journaled, and is adapted to be connected to a register or other suitable device for indieating the measurements taken. Between-v the register R and the bar 22 a brass 'disk 4() is fixed to the axle'2`9 and'bears the indicia Yshown in the drawings, the indicia being designated Vat 40a andv representing inches.

. ALA.' tensioning devicecoacts with the driving wheels and includes a screw threaded shaft 41, operatively mounted in va threaded of the main lframe. At its outer end the screw shaft 41 has connected thereto v an i operating handle 43 andbetween the operating handle and theuthreaded bearing alocking V.device 44 is provided and has threaded 1connection with Vthe screw and is engagelable with the threaded bearing to releasablyV secure the shaft in any position to which it may be adjusted. The inner end of the Vscrew shaft-carries a tension block 45, the

At its ends the block 45v is bifurcated to `receive tension rollers rotatably mounted Vonpintles, 57 carried'by thewbifurcated porengaged with the cable'or sand line.

tionsmof the block. If desired, thetension rollers may be providedy with peripheral grooves'to better engage the cable or sand line. Itis to be understood also that the driving wheels may or may not be provided with peripheral grooves asl desired. Tension block 45 operates rbetween a pair of bars 21 which serve as guides Jfor the tension block and preventlateral 'displacement thereof.

In operation v.the well measuringY apparatus is positionedon thewell casing and the driving wheels and the tension rollers Vaile 'I e length of the sand lline and consequently the depth ofY the 'well is thus accurately ,measured since the driving wheels are held Vin positive engagement with the sandline and move in correspondence therewith at all times. The, accuracy ofthe measurement' thus obtained is due in a large meas- Vure to the fact that the driving wheels are Vpositively. constrained to partake of motion in the same degree vby virtue of the action of the eccentric disks and the eccentric strap.

'Moreoven in view of the interposition of the ball bearing the disk and strap operate to constrainthe wheels to partake of corresponding motion with maximum efficiency,

whereby the tendency of the cable or sand line to slip by the wheels is reducedY to a minimum ,and this'especially in viewo't the laction of: the tensioning device. Y y The register serves to indicate measurements made by the device and the brass disk indicates the increments in inches to be added to the measurements indicated by the register.

I claim l. In a well measuring apparatus, a'frame,`

a plurality of axles rotatably mounted in the frame, drivingwheels mounted 0n the axles, disks fixed to said driving wheels eccentrically thereof, and an eccentric strap coacting with the disks.

frame, a plurality of axles rotatably mounted in the trame, driving wheels mounted on the axle, disks fixed to said driving wheels eccentrically thereof, an eccentric strap coacting with the disks, andball bearings between the eccentric strap and said disks.

3. InV aV well Vmeasuring apparatus, a frame, driving Hwheels carried by the frame, means for constraining said driving wheels to corresponding motion, a register driven from one of the driving wheels and indicating measurements made by kthe device, and a disk iixed to the kdriving wheels from which the register is driven and bearing indicia yto indicate the incrementsy to be added to the measurements of the register.`
